Specication forming part of LettersA Patent No. 122,381, dated January 2, 1872 antedatecl December 16, 1871.

Y ence being had to the accompanying' drawing forming a part of this specification.

My invention consists in a combination of feedrollers, presser-rollers, drying-rollers, folders, and brushes and paste-troughs, for the purpose of rapidly making carpet-linings, composed of two continuous sheets of paper with a sheet of filling between them. p

In the drawing, Figure l represents a side elevation; Fig. 2, a plan View; Fig. 3 shows the .folder for folding over the double-lap bindingf7 shown in Fig. 5. Fig. 4 shows the 'folder forfolding in the edge of the und er sheet of paper in the turned-in binding,v shown in Fig. 7. Fig. 5 is a section showing the double p lap binding.77 Fig, 6 shows the welt-binding.

Fig. 7 shows the turned-in binding.77 Fig. 8 shows the stripbinding' It will be seen that my machine is capable `of makingfour or more different kinds of lining.

In the drawing, A represents the general frame-work of the machine, oblong square in n shape, and may be about three feet high and wide, and about twelve or fifteen feet long. B B are the two paper-feed rollers; C is the filling or wadding feed-roller; D D are the feed-bobbins for the double-lap binding; F Fl F2 are the brushes for applying the paste to the outer edges of the two sheets of paper when the double binding is used, and Gris the paste-trough, used in connection with these brushes. H H are the folders which fold the binding over the edges of the paper; I I are the folders which .turn in the edges of the nnder sheet of paper in making the turned-in binding;` J J are the bobbins which carry the strips of paper or cloth used in the welt-bind ing7 or strip-bindingf7 K is the paste-trough for pasting the strips 5 L is a large roller, revolvin g in and nearly iilling the trough K; M M, presser-rollers; N O P are three large dryingrollers, at the delivery end of the nia-chine, Q is the last or discharge-roller. The various rollers and brushes are properly revolved by belts in any suitable and obvious manner.

I will describe the mode of operation in mak in g each ofthe four kinds of carp et-lining shown in the drawing.

In makin gthe carpet-liningwith the Fdoublelap binding, descri bed in my patent of September 27, 1870, I first put twocontinuous sheets ofsuitable paper upon their feed-rolls B B', and a continuous sheet of filling upon its feedroll C, and the strips of 'cloth or paper for binding upon the bobbins D, and fill the paste-troughs Gr with a suitable paste. The machine is then put in motion. Until the first two or three yards of the lining have been made the operators, by hand, feed forward the lining un'til it is taken between the feed and presser-rollers M M. As vthepaper leaves the feed-rollers it vpasses between the lips of the brushes F, which apply the paste to the edges of the paper, as lshown at a', Fig. 2. The paper or cloth strips on the bobbins D then pass through the folders H, which fold them over the paper on the edges where the paste has been applied 5 the presser-rolls M M then press closely the folded strips up on the paper, which thus becomes securely fastened and. closed at both edges. The lining is then passed over the drums N O P and roller Q, ready to be baled.

In making carpet-linin gwith the welt-bin din g,77 as shown in Fig. 6, I dispense with the use ofthe brushes F and paste-trough G. I use only three strips of paper or cloth, one at each edge and one at the center of the lining. These strips pass under roller L, and are thus'immersed in the paste which is contained by the trough K 5 they then pass onward, between the two sheets of paper,`one at each edge, between A the sheets of paper past the edges ofthe filling, and continue to go forward with the paper and the filling until they all pass between the presser-rollers M M, which press and stick to-V gether the strips, paper, and iillin g, and carry forward the completed lining to .the drying rollers N O P.

It will be seen that the brushes F are of a -peculiar construction, the brush at each end of Vthe trough being really a triple brush; that Vbrush marked F revolving vertically in the paste .for the purpose of feeding the brushes F1 and F2. These brushes F1 and F2 are in a horizontal plane, and have their faces touch- Para rr rrrcn.

ing, so that when the paper passes between them it will be pasted on both sides. These brushes may be used together, or the brush F2 may be unshipped; they mesh with brush F, and are revolved by it like bevel-gearing.

In makin g the turned-in 7 binding, shown in Fig. 7 the under sheet of paper must be about two inches wider than the upper, to allow about an inch to be turned in at each edge. Thebrush F2 is unshipped, in this case, and the folders I are used to turn in the edges. As the paper goes forward the under face of the brush Fl applies the paste to the upper surface of the folded edge. The presser-rollers M then press and stick together the two sheets of paper with the lling between them, as shown in Fig. 7.

In making the strip-binding lining, shown.

in Fig. 8, (for which I have prepared another specification and application,) I dispenseI with the use of the folders, brushes, and trough G, and use instead four, six, or more narrow strips, a a', of paper or cloth disposed in pairs. When six of these strips are used, as shown in the drawing, Figs. 1 and 2, three of them pass between the iilling or wadding and the undef sheet of paper, and three (but not opposite) between the wedding and the upper sheet of paper. Being well pasted on both sides these strips stick as well to the wedding as to the paper, when they are passed between the presser-rolls.

What I claim as my invention is l. The mitre-brushes F F1, in combination pet-lining, I have hereunto signed my name y this 3d day of October, 1870.
